This extremely rare Audemars Piguet Royal Oak Tourbillon was released in celebration of the Royal Oak's 25th Anniversary in 1997. It is believed that only five of these watches were produced in platinum. These pieces feature a hidden crown on the caseback and a vibrant purple dial with a tourbillon display. For the movement geeks out there, the movement is the famous self-winding tourbillon calibre 2875, which uses a hammer rotor instead of the typical full circle rotor. All credits to @the_keystone
